How many mg of a metal containing 62 percent nickel must be combined with 4 mg of pure nickel to form an alloy containing 78 percent nickel? Which of the following equations could be used to solve this?

Answer:

okay I'm not 100% sure but I have a good idea (it's okay if u remove me it's just an educated guess)

89%

Step-by-step explanation:

if there were 100 students that would mean 1 student represented 1% of the results. so if there were 50 students 1 student would represent 2% of the results. so if two students were removed then that would mean the result would improve by a total of 4% which would get you 89%

I just plugged in the numbers.

Answer:

1: Tip, $2.23

2: Tax, $0.74

3: Total, $17.87

4: Split, $5.95

Step-by-step explanation:

To find the tip, you must multiply the tip percentage by the bill, (which has not been taxed yet). The tip is 15%, which is equivalent to 0.15. The tip multiplied by the bill (0.15×14.90) equals $2.23.

To find the tax, you do the same as you did with the tip. The tax is 5%, which equals 0.05. The tax multiplied by the bill, (0.05×14.90) equals $0.74. The total cost is the bill, tip, and tax added together, (14.90+2.23+0.74) equals $17.87. To find out how much each person will pay equally, you must divide the total bill by the amount of people, (17.87÷3) which equals $5.95.

Answer:

Step-by-step explanation:

area of square=8²=64  m²

radius of each circular arc at the corner=8/2=4 m

area of  four circular arcs=4×1/4 ×π×4²=16  π m²

area of shaded region=64-16π=16(4-π)≈13.73 m²

Answer:

The median is 7.

Step-by-step explanation:

In order to find the median, you need to ut the numbers in either least to greatest form, or greatest to least (FIRST).

I'm gonna do both as an example.

Greatest to least:

14, 13, 9, 9, 7, 5, 3, 2, 1

Least to greatest:

1, 2, 3, 5, 7, 9, 9, 13, 14

It is REALLY important that you use ALL of the numbers you are given, even if there are two or more of the same number.

The next thing you need to do is find the number that is in the middle.

It will be the same for both least to greatest AND greatest to least.

You can either count one from either side, going in a pattern, OR you can count how many there is, divide it by 2, and whatever answer you get, count that many times over from one side.

In this case, your answer goes like this:

since there are 9 numbers, and 9 is not an even number, you will have only one median. Having 2 medians IS normal and it IS ok.

In this case, you want to go down one number (from 9) and divide that. So you do 8 divided by 2, which is 4. Count that many times over and you have your answer, 7.

I hope this helped you!

Answer:

Step-by-step explanation:

[tex]6 \frac{1}{5 } \: = \: \frac{31}{5} [/tex]

Hence,

31/5 % of 425ml

[tex] = 425ml \times \frac{ \frac{31}{5} }{100} [/tex]

[tex] = 425ml \: \times \frac{31}{5} \times \frac{1}{100} [/tex]

[tex] = 85ml \: \times 31 \times \frac{1}{100} [/tex]

[tex] = \frac{2635}{100} ml[/tex]

= 26.35 ml (Ans)

Step-by-step explanation:

Answer:

Step-by-step explanation:

1.)

3x=3

x=1

2+y=0

y=-2

solution: (1,-2)

2.)

6y = -36

y = -6

-4x+12 = -12

-4x=-24

x = 6

solution: (6,-6)

Answer:

Top: x=1, y= -2

Bottom: x= 6, y= -6

Step-by-step explanation:

Top:

Isolate x for y: 2(3+y) + y = 0  

Simplify: 6+3y=0

Isolate y for 6+3y=0: y = -2

For x= 3 + y: x = 1

Bottom:

Isolate x for : -4x - 2y= -12:     x= [tex]\frac{-6 + y}{2}[/tex]

Simplify: 6y+ 12 = -24

Isolate y for 6y+ 12 = -24: y = -6

For x= [tex]-\frac{-6 -6 }{2} = 6[/tex] : x = 6
